Interpretation of infrasound generated by erupting volcanoes and seismo-acoustic energy partitioning during strombolian explosions
Infrasonic signals provide a valuable tool for the study of volcanic eruptions because volcanoes generate the majority of their acoustic energy in the infrasonic bandwidth and infrasound is only slightly affected by propagation filters, transmission losses, dispersion, and instrument site responses. Though changing atmospheric ...
Behavior of the atomic oxygen 5577 Ångström emission intensity at mid-latitudes: a climatological view
A global mid-latitude study of the atomic oxygen green line emission intensity at 5577 A has been undertaken with the goal of developing a climatological understanding of the emission behavior and its usefulness as a tracer for the atmosphere near 97 km. Long-term observations have been analysed at nine stations covering ...
